Data Matrix, also known as Data Matrix ECC200, is great 2-dimensional matrix barcode to store different data up to 2,335 alphanumeric characters.

Java Data Matrix generator provides other setting pages for more detailed information on how to generate and create high qulaity 2D Data Matrix barcode images in Java programming.

Java Data Matrix image setting concentrates on setting Data Matrix image color, resolution, rotation, bar lignment and so on;

Java Data Matrix data encoding concentrates on setting Data Matrix data encoding and valid data length in Java projects.

Properties to change the Size of Data Matrix in Java

Overall Properties to Influence Data Matrix Size in Java

  • uom: Unit of meature for all size related settings in the Java barcode library. Valid values: 0: pixel; 1: inch; 2: cm.
  • formatMode: Java Data Matrix module format.
  • X: value of Data Matrix module width and height, default is 3 pixel.

Data Matrix Width Related Settings in Java

  • barcodeWidth: Generated Data Matrix barcode image width, default is 0 pixel.
  • leftMargin: Data Matrix image left margin size, default is 0.
  • rightMargin: Data Matrix image right margin size, default is 0.

Data Matrix Height Related Settings in Java

  • barcodeHeight: Generated Data Matrix barcode image height, default is 0.
  • topMargin: Java Data Matrix image top margin size, default is 0.
  • bottomMargin: Java Data Matrix image bottom margin size, default is 0 pixel.

AutoResize for Data Matrix Size in Java

  • autoResize: Auto resize the generated Data Matrix barcode image in Java, especially setting the width and height

More Specific Guide on How to Adjust the Data Matrix Size

      //Set a Data Matrix object in Java applications
      DataMatrix barcode = new DataMatrix();

Then, modify the following properties you may need:

Set Format Mode to change the Data Matrix size in Java

If format mode you set is conflict with the encoding data you set, the library can automatically set the proper mode in Java


Adjust Unit of Measure of Java Data Matrix


Adjust X in Java Data Matrix

As a 2D barcode in Java, Java Data Matrix is obviously the bar module width and height is the same. For this reason, when ajusting the X, it will change the size of the module with changing the height and width at the same time in Java applicaions
